Alzheimer’s Testing Warning: Don’t Rush for Memory Tests, Here’s When You Actually Need Them

With rising awareness around brain health, more people are becoming concerned about memory lapses and their possible link to Alzheimer’s disease. But experts caution against jumping to conclusions or tests too quickly. Not every instance of forgetfulness signals a serious neurological condition, and unnecessary testing can lead to anxiety, misdiagnosis, and avoidable medical costs. “Different people have different reasons for memory problems. An occasional forgetfulness, especially in a younger person, is usually related to lifestyle and psychological factors such as stress, burnout, sleep deprivation, anxiety, or nutrition. Such factors can change your perception and attention temporarily and, in general, are not a sign of neurodegenerative

illness,” Dr. Asma Bibi, Consultant Hematopathologist, Consultant NCGM Chief of Laboratory, Chennai and Kerala, Neuberg Diagnostics Pvt Ltd, told Times Now Health.

Not all memory issues mean Alzheimer’s

Occasional forgetfulness is common, especially among younger individuals. Factors such as stress, burnout, poor sleep, anxiety, and nutritional deficiencies can temporarily affect memory, focus, and attention. For example, forgetting where you placed your keys, walking into a room and forgetting why, or missing minor details during busy or stressful days. These are typically linked to lifestyle or psychological factors - not neurodegenerative disease. In such cases, experts advise against undergoing Alzheimer’s biomarker testing.Also read: Anant Ambani Weight Loss Journey: Lost 108 Kg, Here’s Why He Regained It

When should you consider Alzheimer’s testing?

Testing becomes relevant only in specific clinical situations where symptoms suggest a deeper neurological issue. Doctors recommend evaluation if:

• You are above 65 years of age
• Memory problems are progressively worsening over time
• There is a strong family history of early-onset dementia
• Cognitive decline begins to interfere with daily life

In these cases, early diagnosis can help manage symptoms and slow disease progression. “In such cases, one has to go further in the investigation of the symptoms to learn the cause and change of symptoms,” said Dr. Asma.

How does Alzheimer’s testing work?

Modern diagnostic methods focus on detecting abnormal levels of two key brain proteins - amyloid and tau. These proteins naturally occur in the brain, but when they accumulate abnormally, they are linked to Alzheimer’s. A newer method, blood-based biomarker testing using chemiluminescence immunoassay (CLEIA), allows doctors to detect these changes through a simple blood sample. This technology helps identify early disease-related changes, differentiate Alzheimer’s from other types of dementia, and further guide neurological evaluation. However, according to Dr. Asma, these tests are not meant for routine screening or preventive use, especially in healthy individuals without symptoms. “These tests should not be considered as preventive measures or tools for routine screening, especially for younger individuals. Their main benefit is targeted use, where clinical symptoms and risk factors indicate that further investigation is necessary,” she said.

Early warning signs of Alzheimer’s you must not ignore

Recognizing the right symptoms is key. Some common warning signs of Alzheimer’s include:

• Repeatedly asking the same questions
• Difficulty remembering recent events but recalling older memories clearly
• Forgetting familiar names or faces
• Getting lost in familiar places
• Trouble completing everyday tasks
• Mood and behavioural changes such as irritability or depression

If these symptoms persist for over six months and begin affecting daily functioning, it’s important to consult a neurologist. According to Dr. Asma, one of the biggest mistakes people make is testing too early or unnecessarily. According to experts, including leading neurologists, the timing of testing is just as important as the test itself. Unnecessary testing not just creates false alarms but also leads to overdiagnosis and causes emotional stress. On the other hand, timely testing in the right individuals can significantly improve disease management.
